I think it was said they were longer but I'd like to know for sure too as my lts will go on in a couple of weeks.

 

yes they are longer the ones i got for rear o2's on a corvette where 60" long if i remember correctly

 

ya they are way long, i had to double mine over twice and ziptie like the instructions said

 

Did you check the eng fuse? Its a 20 amp fuse located under the hood in the fuse box closest to the front of the car I believe it will throw p0102 and mayb some other things. If not use a volt meter and with the key on unplug the maf ground the volt meter and check each of the wires on the plug one should be ground another 5v and the other 12v

 

so what's the benefit of using the corvette o2s over the stock 02s?

 

they are longer for longutbes. to me it didnt make sense to spend 50 bucks or whatever on extensions and my 100k mile o2 go out and i still need to buy new ones. so instead i got two new ones that are long enough on their own.

 

you are going to throw codes if you don't get the rear O2s tuned out or put sims in there. and even the sims aren't always reliable. i had sims in mine and i got an "over current" or something in both banks, got the rear O2s tuned out and the SES went away.

 

how many 02s to long tubes need?

 

just the front two which the computer uses for engine management, the rears are plugged with sims or tuned out(which is the best way to go and what i did). the rears are only there to make sure the cats are doing their job so they arent necessary.
